List of Income tax ward/circle No. of AO

Hi everyone, Can you advice as I am looking for the list of The Wards/circle No. of AO in Gujarat - Ahmedabad. If anyone is aware about the same then help. I think no such list is available for general public. I highly recommend to publish such list as in UK economy the HMRC(UK's Govt.) every procedure including very formalities like such ward no.s & all is generally available to public at large. Thanks in advance for any positive reply. Ashish Joshi
